Your local weather report helps with
immediate weather decisions but has significant
limitations when it comes to planning beyond a few days. In contrast, dryday™ provides a long
term
tool where every other weather service stops.

dryday™ weather forecasts
indicate, months in advance, the dates in which there
is
little risk for rain (or snow).

The dryday Advantage

Over the past ten years, dryday users have enjoyed
significant odds on their side with accuracy up to 87%.

Planning on your own puts you at additional risk

During that same time period, dryday forecasts outperformed planning on your own by a
factor of
almost three to one. This means that if you were planning with dryday forecasts during
that
period, roughly three out of four dryday forecasts would have provided you better odds
over planning on
your own.

The opposite is also true, if you were planning on your own, you would have been at a
disadvantage around 75% of the time. You could be
planning right in the middle of a period with a high risk for rain.

How We Forecast Long Range Weather

dryday™ forecasts are created using a dynamic model of the atmosphere,
based on meteorological forces that have been proven by extensive testing to be acting upon our
weather.

The way our forecasts are made is similar to how tidal charts are created.
The tides are caused by
forces (gravitational and centrifugal) between the sun, earth and moon. They are very consistent
and
can be accurately predicted in the long term. And just like a tidal chart, our weather
forecasting
model can go out as far as 18 months with no erosion of accuracy.
